  • Immune Memory Formation Seen in Early Stages of Viral Infection
    In an acute viral infection, most of the white blood cells known as T cells differentiate into cells that fight the virus and die off in the process. But a few of these "effector" T cells survive and become memory T cells, ensuring that the immune system can respond faster ...More
